ABSTRACT
The typical single-engine flight training airplane has a throttle and a mixture control for the engine power and a control for carburetor heat or alternate air source in case of icing problems. More complex airplanes may have a control of the propeller’s pitch (RPM), and possibly a control of the engine’s temperature with adjustable cowl flaps. Even larger radial engines may have a throttle, propeller, mixture, carburetor heat or alternate air source, cowl flaps, and oil cooler flap controls. If the airplane has two or four engines, the number of controls are proportionally increased.
